STAMP-CANCELER.

SPECIFICATION forming part of Letters Patent No. 351,348, dated October 19, 1886.

Application filed September 4, 1884. Serial No. 142,198. (No model.)

To all whom it may concern:

Be it known that we, JOHN H. G. \VITT, a subject of the Emperor of Germany, having resided one year last past in the United States, and made oath of intention to become a citizen thereof, and JACOB J. F. Porr, a subject of the Emperor of Germany, both residing in the city and county of Philadelphia, State of Pennsyl Vania, have invented a new and useful Improvement in Stamp-Oancelers, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 represents a side elevation of a stamp canceler embodying our invention. Fig. 2 represents a vertical section in line 00 00, Fig. 1. Fig. 3 representsa side elevation of a detached portion.

Similar letters of reference indicate corresponding parts in the several figures.

Our invention consists of improvements in stamp-cancelers, as will be hereinafter fully set forth and claimed.

Referring to the drawings, A represents a head having a serrated face, a, and B represents a cylinder, to whose lower end said head is secured. In the wall of said cylinder are diagonal slots b, into which project the ends of a horizontally-arranged pin, 0, the latter being connected with a stem, D, at the bottom of the knob or handle E of the device.

Surrounding the cylinder B is a cylinder, F, which has its lower edge serrated, as at 0, and in said cylinder is a vertical slot, d, into which the pin 0 projects. If desired, vertical slotssuch as d-Inay be formed on opposite sides of the cylinder F, so that each end of the pin 0 is fittedin one of said slots.

G represents a cylinder, which incloses the cylinder F, and is secured thereto, thus covering the slot or slots (1 and end or ends of the pin 0, the top of said cylinder E being guarded by a sleeve, H, which depends from the handle E around the stem D.

Interposed between the top of the head A and bottom of the handle or stem thereof is a spring, J, which serves to ease the blows of the canceler during the operation of the same and restore the parts to their normal position.

In the cylinder F, near the bottom thereof, is a horizontally-extending slot, 0, into which projects a pin, K, which is connected with the cylinder B, and for the purposes of strength fixed to the head A.

The operation is as follows: The canceler is grasped by the handle E and directed by a blow on the stamp to be canceled. As the handle and sleeve H are permitted to descend and the pin 0 follows the motion thereof, and owing to the action of said pin .0 in the diagonal slots bof the cylinder B and the pin Kin the slot 0 of the cylinder F, said cylinder B is caused to rotate, and the serrated face a grinds or cuts away the portion of the face of the stamp with which it is in contact, it being noticed that the serrated edge 0 of the cylinder F takes firm hold of the stamp, so that the canceler surely retains its hold on the stamp' during the grinding or cutting action thereon, and the stamp is reliably canceled. When the canceler is raised, the spring J restores the parts to their normal positions. iVhile the pin 0 connects the inner cylinder, B, with the stem D of the handle, its projection into the slot (1 also serves to guide the cylinder B and assist in connecting the cylinders B F; but the pin K, which prevents the descent of the head A and cylinder B, is sufficient to connect said cylinders B F.

Should the slot- 6 be made deeper than the thickness of the pin K, a slight vertical movement maybe imparted to the head A and cylinder B, so that the serrations cut or grind the stamp to a greater depth; but this is scarcely desirable, and if the slot (1 is made of diagonal form in reverse order to the slots 2) and the cylinder F disconnected from cylinder G the cylinders B F will rotate on the stamp in opposite directions, and the cutting-edge of each cylinder act on the stamp to destroy or cancel the same.

The bottom of the inner cylinder, B, is also serrated, thus increasing the grinding or cutting action on the stamp.

Having thus described we claim as new, and desire to secure by Letters Patent, is-

our invention, what A stamp-canceler composed of the head A, bined substantially as and for the purpose set secured to the slotted cylinder B, the said cylforth.
